The Spratt Controlwing
Flying Boat — plans and manual
The Spratt Controlwing Flying Boat — plans and manual
George G. Spratt’s Controlwing flying boat was developed from 1939, with plans drawn up in 1972–1973. Bill Wolfe used these drawings to build N107GW in the late 1990s. Sadly, he died in 2014.
Bill extensively annotated the plans and marked many personal changes to the original Spratt 1973 design, and kindly made them, and an 84 page construction and information manual with additional notes and drawings, available for non-commercial use.
See the web site www.georgespratt.org for videos of Spratt Controlwing flying boats, the Spratt and Controlwing History, the Spratt–Wright connection, plus other historic materials and general information.
The plans and manual are both in two parts, all Adobe PDF files:
|controlwing-plans-part1.pdf||(11 pages,||12 MB)|
|controlwing-plans-part2.pdf||(20 pages,||13 MB)|
|controlwing-manual-part1.pdf||(79 pages,||12 MB)|
|controlwing-manual-part2.pdf||(5 pages,||15 MB)|
The pages in the two parts of the plans are as follows:
Thanks, too, to A&B Reprographics, Inc., who digitized the plans and kindly provided them for this site.
